- Italy Application June 28, 1938, Serial` No. 216,405 In Italy January19, 1938 'I Claims.

It has already been proposed to use glass slabs or .blocks tor theconstruction of walls and illuminated covers, wherein these slabs areconnected together by joints of reinforced concrete. The slabs inquestion are generally formed by two shallow dished members assembledtogether by putty or the like to form closed'hollow. bodies.

For the formation of the joints the slabs are located at a. considerabledistance apart and the intervening space lled with cement andreinforcing bars.

Walls and covers formed in this manner require a. very large quantity ofglass as also the sides as well as the front and back faces of theblocks are formed of glass and this increases the cost of manufactureand the difficulties of jointing as it is necessary to'space the slabsexactly.

The invention has for its subject a novel construction of slabs of thistype of which the jointing becomes very simple and which enables aconsiderable economy in glass to be effected as these slabs are formedof .two plates of glass having end ridges forming a suitable recess forreceiving lateral connecting bands of card-board, fibre, Celluloid orthe like material forming the sides of the hollow slabs or blocks, saidend ridges also forming projections adapted to constitute joint cavitiesbounded on both sides by two' contiguous bands of the pliant materialforming the sides of the blocks or slabs.

Two forms of construction in accordance with the invention are shown byway of example in the accompanying drawing, wherein:

Figure 1 shows at the upper portion a front view of a translucent wall,and in the lower portion, a pian view of a. translucent cover.

Figure 2 is a section on the line A-B of Figure 1.

Figure 3 is a similar view on Figure 1.

In the construction shown, the slabs or blocks are each formed by twoglass plates |,`2 of which the ends have marginal internal recesses inwhich the line C-D of are secured, by means of putty or the like, bands(Cl. 'l2-42) ridges nearly come into contact. The recesses in which thepliant bands are secured, form between each block a cavity to beoccupied by the cement 1 which may be reinforced with iron members.

In the construction shown in the lower portion of Figures 1 and 2 and inFigure 3, which can be used for forming transparent covers, the

two plates I and 2 are of different thicknesses.' as the upper plate 2must be capable of supl0 porting loads. The lower plate, on thecontrary,A is provided withl end ridges 8, 8 which are longer than theridges 9, 9 of the upper plate 2, so that when two contiguous plates areplaced side by side a free opening is left at the top through 15 whichthe cement for the joint can be run.

It will be seen clearly that the construction of Walls and `covers withthe use of slabs or blocks according to the invention can be effectedvery'easily as the shape and dimensions of the 20 end ridges ofthe glassplates automatically fix the distance between the slabs and thethickness of the joints. 'I'here is effected a considerable economy inthe amount of glass which is necessary as the sides of the slabs areformed of a 25 cheaper material.

It will bey understood that the shape, size and joint recesses of theglass plates may be varied without departing from the scope of theinvention.

What I claim is:

1. A glass slab or block for the construction of translucent walls andcovers, comprising a pair of glass plates having internal marginalrecesses and arranged to form the front and back faces of the slab,non-vitreous plates engaged in said recesses and disposed between saidglass plates to form therewith a closed hollow block or slab of whichsaid non-vitreous plates form the sides, and mar- 40 ginal ridges onsaid glass plates extending beyond said sides in such a manner that themarginal ridges and non-vitreous sides of adjacent slabs or blocksconstitute a cement receiving joint space.

2. A glass slab or block for the construction of translucent walls andcovers, comprising a pair of glass plates having internal marginalrecesses and arranged to form the front and back faces of the slab,flexible non-vitreous plates engaged in said recesses and disposedbetwen said glass plates to form therewith a closed hollow block or slabof which said non-vitreous plates form the sides, and marginal ridges onsaid glass plates extending beyond said sides in such a manner that themarginal ridges and non-vitreous sides j of adjacent slabs'or blocksconstitute a-cement receiving joint.

3. Slab according to claim 1, wherein the glass plates are of identicalform.

4. A glass slab or block for the construction of translucent walls andcovers, comprising a pair of glass plates `having internal marginalrecesses and arranged to form the front and back faces of the slab,non-vitreous plates engaged in said recesses and disposed between saidglass plates to form therewith a closed hollow block or slab of whichsaid non-vitreous plates form the sides,

and marginal ridges on said glass plates extending beyond said sides,and in which one glass plate is thicker than the other glass plate andthe latter has its marginal ridges longer than those of themst-mentioned plate, whereby when the longer marginal ridges of adiacentslabs touch one another there is formed a joint space which is open atthe side of the shorter marginal ridges.

and is bounded at the sides by said non-vitreous plates.

5. A wall structure of slabs according to claim 1, having adjacent slabsarranged with their marginal ridges in approximately abuttingrelationship and the joint spaces filled with cementlng material.

6. A weight sustairnng cover structure formed 'of slabs according' toclaim 4, disposed with the thicker glass plates of the slabs on theweight sustaining side of the cover and the joint spaces between theslabs filled with cementing and reinforcing material.

'7. A weight sustaining cover structure formed of slabs according toclaim 4, disposed with the thicker glass plates of the slabs on theweight sustaining side of the cover and the joint spaces between theslabs filled with cementing and reinforcing material.
